A king emerges from a hidden door in a city park, startling two children sheltering from the rain. No sooner does he push a map and some strange objects into their hands than he is captured by hostile forces that whisk him back through the enchanted door. Just like that, the children are caught up in a quest to rescue the king and his kingdom from darkness, while illuminating the farthest reaches of their imagination. Colored markers in hand, they make their own way through the portal, under the sea, through a tropical paradise, over a perilous bridge, and high in the air with the help of a winged friend. Journey lovers will be thrilled to follow its characters on a new adventure threaded with familiar elements, while new fans will be swept into a visually captivating story that is even richer and more exhilarating than the first.

Broadening his palette, Becker fills his book with myriad colorful details that will reward sharp-eyed fans. At the same time, his ink and watercolors evoke different kinds of architectural wonders. Part Indiana Jones, part Avatar: The Last Airbender, this book proves to be more exciting than its Caldecott Honor predecessor… Breathtaking in scope, consider this a wordless testament to the power of not just imagination, but art itself; picture books rarely feel this epic.
